How To Cancel a Program on the Workchoice WC2021 Digital Timer
The
Workchoice WC2021 is (or perhaps by the time you read this, "was")
Wal-Mart's take on a cheap digital light or appliance timer. It's so cheap, in fact, that
whoever designed it forgot to include a way to cancel the operation of
all timer programs. A button to manually control the timer's on or off
state is provided, but its overriding effect only lasts until the next
timer event occurs. In other words, it's not permanent. Sometimes
you want to stop a timer from running any of its programs for a period
of time.
There is actually a way to stop any
of the programs from running without having to use the reset button,
which would destroy all the stored programs. Press the "COUNT DOWN"
button once to enter the countdown timer mode. There is no need to set
a time. Press "COUNT DOWN" again to start the timer running. Moments
later, press the OVERRIDE button (on top of the timer's case) until the timer display indicates that
it's off.
This will maintain all the programs
you've set in the timer's memory, but they will not run automatically
until you press one of the other three function (dusk to dawn, custom
on/off or vacation) buttons.
The exceedingly clever person
who designed this timer also thought it a good idea to use obnoxiously
bright blue LEDs in each function button and that putting tri-wing
screws on the bill of materials would actually keep people out of it. (Note: it's actually dangerous to open this timer up any time it's plugged in since the power supply is a capacitive dropper.
There is absoultely no isolation between the power line and the timer's
electronics. So don't do that. The previously linked Harbor Freight bit
set will technically get you in there, but you'd have to ream out the
recessed holes in the timer's case before the bits would fit.)
Other Stuff
A small NiMH battery keeps the timer
running and its memory intact for somewhere around 24-48 hours depending upon its state of charge and overall health. The
latter will decline over time. I'd imagine it is possible to find a
cheap replacement from the usual friendly Chinese sellers on eBay.
